: Bacteriophages infecting the genus play a crucial role in microbial ecology and have potential applications in biotechnology and medicine. Despite their importance, significant gaps remain in our understanding of their lysis modules. This study aims to address these deficiencies by analyzing the genomic diversity and lysis module organization in phages.

The virulence of Streptococcus mutans, a key caries pathogen, is partly explained by its rhamnose-glucose polysaccharide (RGP) and its sucrose-dependent and -independent adhesion mechanisms. Given their role in comorbidities, this study investigates the diversity of S.

Methods: A cross-sectional study was carried out in 2014 among the participants of a cohort on cerebral and functional aging in France at their 25-year follow up (the PAQUID cohort). Nutritional status (Mini Nutritional Assessment [MNA]) and oral health status (number of decayed, missing, and filled teeth [DMFT], number of posterior occluding pairs, xerostomia [Xerostomia Inventory], and prosthetic rehabilitation) were recorded at the participants' living places by two dentists.

There has been little exploration of how phages contribute to the diversity of the bacterial community associated with winemaking and may impact fermentations and product quality. Prophages of , the most common species of lactic acid bacteria (LAB) associated with malolactic fermentation of wine, have been described, but no data is available regarding phages of with true virulent lifestyles. The current study reports on the incidence and characterization of the first group of virulent oenophages named Vinitor, isolated from the enological environment.

Design: We evaluated Bruker MALDI Biotyper for the identification of 92 clinical oral isolates of probiotic interest (31 Streptococcus salivarius and 61 Lactobacillus spp.) by comparing direct colony method with on-plate formic acid extraction.

Increasing resistance and changes in the spectrum of Candida infections have generated considerable interest in the development of new antifungal molecules. The use of antimicrobial peptides (AMPs) appears to be a promising approach. Frog skin AMPs (such as dermaseptins) have shown antimicrobial activity against several pathogens.
